प्रश्न
From their examination of the structure of DNA, What did Watson and Crick infer about the probable mechanism of DNA replication, coding capability, and mutation?
उत्तर
Inference of Watson and Crick on DNA replication:
They concluded that each of the DNA strand in a helix act as template during DNA replication leading to formation of new daughter DNA molecules, which are complementary to parental strand, (i.e., Semi-conservative method of replication).
Inference on coding capability:
During transcription, the genetic information in the DNA strand is coded to mRNA as complementary bases, (except for uracil in place of thymine in RNA).
Inference on mutation:
Any changes in the nucleotide sequence of DNA leads to corresponding alteration in aminoacid sequence of specific protein thus confirming the validity of genetic code.
